Joint mechanism for armchairs and the like essentially characterized in that it is of the type that is constituted by two angular plates articulated together also comprising a trigger that is hinged to one of said plates with the help of a spring is anchored on a arm attached to the other through notches that establish as many articulation positions between the aforementioned plates, the aforementioned trigger has a pivot which, depending on the rotation of the plate to which the trigger itself is articulated, runs along a diagonal ramp established on the opposite plate coinciding with the anchoring of the notches that the latter carries in the arm of the latter and why the anchoring of the extreme notch of the trigger in this arm disposes said pivot on the upper edge of said ramp being subjected to a sliding through the rotation of the latter. The corresponding plate that causes the release of the trigger of the arm and anchoring until an inverse rotation of this plate establishes the coupling of said notches in the arm itself.
